Overview

The Samsung QH55C is a 55-inch UHD 4K display for digital signage, built on a VA panel with 700 nit typical brightness and a 28.5 mm depth. Its even 11.5 mm bezel and centred VESA mounting points keep portrait installations neat and stable. Three HDMI inputs, one DisplayPort input and RJ45, RS232 and Wi-Fi connectivity suit lobbies and corridors that run content around the clock.

What the QH55C is built for

The Samsung QH55C is a 55-inch UHD 4K signage display from the Crystal UHD Signage QHC series, designed for businesses that show content for long hours in fixed locations. It uses a VA panel at 3,840 x 2,160 resolution with 700 nit typical brightness and a 4,000:1 contrast ratio, so text, logos and video stay readable in bright reception areas.

Slim body, even bezel and centred mounting

At 28.5 mm deep, with a set weight of 16.9 kg, the QH55C sits close to the wall. The bezel measures 11.5 mm on all four sides, so the frame looks the same in landscape and when the screen is rotated to portrait. The VESA pattern is 200 x 200 mm and its mounting holes are centred on the back, which spreads the load evenly and keeps the display from tilting when it is turned for portrait use.

A Slim Fit wall mount is compatible with the display but must be purchased separately. The WMN-B50SC wall mount and STN-L4355C stand are listed as optional accessories for this model.

Connectivity and control for managed networks

Video inputs: three HDMI inputs (HDMI version 2) and one DisplayPort 1.2 input, with HDCP 2.2 support.
Control: RS232 in and out, an IR input and an RJ45 network port.
Wireless: built-in Wi-Fi and Bluetooth, with the SmartView+ feature for wireless screen sharing.
Other: two USB ports and a stereo mini-jack audio output, with no audio input listed.

The display runs Tizen 7.0 with 16GB of flash memory. Samsung VXT CMS, a cloud-based content and remote device management service, is available for the model and must be purchased separately. Smart Calibration, managed through the Samsung mobile app, helps keep brand colours consistent when several units show the same logo.

Where it fits in Qatar

A hotel reception in West Bay could use a 55-inch panel to show wayfinding and event listings around the clock, a use that the 24/7 operation rating supports. A private school in Al Wakrah fitting out corridors could mount several units at a consistent height, with the even bezel keeping them visually matched. A medical clinic in Msheireb could place the QH55C in a waiting room, where its 178/178 viewing angles let patients read the content from the side of the room.

What to plan for before you order

The operating range is 0 to 40°C with 10 to 80% humidity, non-condensing. Summer temperatures in Qatar can exceed 45°C, so the display should be installed in an air-conditioned space that stays within this range, and the room's cooling should be checked during the site survey. Power draw is 187 W in on mode and 0.5 W in sleep mode, and the power supply is rated AC 100-240 V at 50/60 Hz. The manufacturer lists energy efficiency class A and reports ENERGY STAR 8.0 and EPEAT certification for the QHC series.

SmartRooms Qatar offers free site surveys to check wall construction, mount height and cable routing before units arrive. Quotations usually follow within one working day, and orders can be placed by purchase order (LPO) or through government tenders, with payment by bank transfer, cheque or purchase order.

Questions about QH55C

Who is the Samsung QH55C designed for?

The QH55C suits organisations that run digital signage in a fixed location for long hours, such as a bank branch in Doha showing queue and service information, or a corporate lobby in Lusail displaying visitor directions. Its 55-inch 4K panel, 700 nit typical brightness and 24/7 operation support make it a practical choice for reception areas, corridors and waiting rooms where a 55-inch screen is the right size.

Is the QH55C suitable for a meeting room or lecture hall?

It is primarily a signage display, so it suits a small meeting room or shared work area where a 55-inch screen is enough. A boardroom or lecture hall with a larger audience will usually need a bigger panel. For meetings, SmartView+ lets a presenter share a screen wirelessly at the start of a session, and the three HDMI inputs cover laptops and media players.

How does it perform in a bright reception area in Doha?

The panel has 700 nit typical brightness and a non-glare finish, which helps content stay readable in a bright reception area. Its 178/178 viewing angles let people read the screen from the side of a room. The data does not rate the unit for direct sunlight or outdoor use, so for a window-facing lobby in Doha or Al Sadd, check sun exposure during the site survey before choosing the position.

What is the operating temperature range, and can it go in a hot room?

The operating range is 0 to 40°C with 10 to 80% humidity, non-condensing. Qatar summer temperatures can exceed 45°C, so install the QH55C in an air-conditioned room that stays within this range, not in an unconditioned corridor, store or outdoor area. SmartRooms Qatar can review the room's cooling during the site survey before you place an order.

Which inputs and control ports does the QH55C have?

The QH55C has three HDMI inputs (HDMI version 2), one DisplayPort 1.2 input, two USB ports, an IR input, RS232 in and out, and an RJ45 network port. A media player or laptop connects over HDMI, while RJ45 links the display to your network. Built-in Wi-Fi and Bluetooth add wireless options, and the supported HDCP version is 2.2.

Does the display have audio, and can I connect external speakers?

It has a stereo mini-jack audio output, but the source data lists no audio input. To play sound through the display, connect that output to external speakers or an amplifier. Plan the cable route during the site survey, particularly in school corridors or large waiting areas where speakers may sit far from the screen.

Can the QH55C be mounted in portrait orientation?

Yes. The VESA holes sit at the centre of the back, so the display does not tilt unintentionally when rotated to portrait, and the 11.5 mm bezel stays even on all four sides. The VESA pattern is 200 x 200 mm. Portrait mounting suits corridor directories and digital menus in Doha cafes; confirm the bracket and the position of the power point on site.

What are the dimensions and wall requirements?

The set measures 1237.9 x 708.8 x 28.5 mm and weighs 16.9 kg, with a packed weight of 21.1 kg. At this weight, the wall and bracket must be rated for the load, so a site survey before installation is recommended. SmartRooms Qatar offers free site surveys to check wall construction, mount height and cable routing. A Slim Fit wall mount is compatible but sold separately.

Which mounting accessories are available for this model?

The manufacturer lists the WMN-B50SC wall mount and the STN-L4355C stand as optional features for this model. A stand suits a free-standing spot such as a reception desk where wall fixing is not possible, while a wall mount suits corridors and feature walls. The Slim Fit wall mount is also compatible but sold separately. Ask for a quotation that includes the accessory you need.

How can I manage several QH55C displays across different sites?

Samsung VXT CMS is a cloud-based solution for content management and remote device management, and it must be purchased separately. It lets you adjust hardware settings and troubleshoot displays remotely, and create and deploy content without prior training. Smart Calibration, using the Samsung mobile app, helps keep brand logos and colours consistent across sites. For a multi-site rollout in Lusail or Al Khor, request one quotation covering the displays and software.

How much power does the QH55C use, and what is its efficiency rating?

The QH55C draws 187 W in on mode and 0.5 W in sleep mode, and the manufacturer lists energy efficiency class A. Samsung also reports that the QHC series holds ENERGY STAR 8.0 and EPEAT certifications. The supply is rated AC 100-240 V at 50/60 Hz. For schools or ministries comparing running costs over long opening hours, these figures make side-by-side comparison straightforward.

Is the QH55C covered by warranty, and how do I order?

SmartRooms Qatar supplies the QH55C by quotation, and it is covered by the manufacturer's warranty. The warranty terms are set by Samsung and are not repeated here, so we confirm them with your quotation. Orders can be placed by LPO or through a government tender, payment is by bank transfer, cheque or purchase order, and a free site survey can be booked before delivery.
